Halecium antarcticum— Totton, 1930: 144 –145, fig. 4.
Remarks. The presence of H. antarcticum in the Ross Sea is not confirmed. According to Peña Cantero (2014b), records based on infertile material, or just with immature gonothecae, are not reliable because of its similarity with H. pseudodelicatulum Peña Cantero, 2014b. This is the case for Totton’s (1930) material.
